Hi,
I've already browsed the archives and found some helpful information about getting low latency in Windows with PD.
Now i'd love to hear about anyone who has been able to get as low as 15-20ms latency in Windows using PD, without getting glitches, preferably in Vista and with external hardware, such as USB or firewire cards. [not that I prefer Vista over XP, but I just happen to have it installed on my new laptop, so if I can get what I need without installing another OS it would be better for me]
I guess I should go for ASIO4ALL and I want to buy an external audio interface, so I was wondering for example if there is any reason for preferring usb vs firewire or viceversa; if any audio interface in particular has proven to work well (or bad so that I avoid buying it) for this purpose; if asio4all performs equally well with external hardware as with built-in hardware......
Any positive or negative experience is welcome; a positive easy-to-reproduce experience is what I'm looking for.
Also, if the same can be achieved with some relatively-newbie-friendly almost-out-of-the-box GNU/Linux distribution, it may be worth trying...
Thanks in advance m.
i am not using windows, but i think roman found a solution (for better latency):
each time you launch pd, go to the list of process and right click on pd: ***REALTIME* - highest possible priority

hei i would recommend first to "tune" your vista for audio, here you go: http://www.focusrite.com/answerbase/article.php/?id=288
the rest maybe you know allready, but anyway, disable/deinstall all fancy vista crap you d'ont need.
and then like pat said, open pd, open your taskmanager, right click on to the pd process and set it to highest priority. You have to do it everytime when you open pd, but there is a small app that can save your prio's. http://www.prnwatch.com/prio.html
but in my opinion, pd still runs the best on linux, so i would recommend a dual boot station.
greetings

i haven't checked on vista, but the rme hdsp hardware behaves very well on winxp (and on linux and most likely on vista as well) . i have a rpm myself, and i can easily go under 15ms. it's been a while, i tried the last time on win xp, but when i set it to 3ms latency, i could achieve a roundtrip of ~7ms. i think, even 1.5ms still works.

with the hdsp hardware, you are on the more secure side, though it is not the cheapest choice.

check the alsa page for supported hardware and maybe ask on #alsa on irc.freenode.net. in my experience, the most hasslefree approach was usually to install jack and start pd with '-jack'. personally, i find ubuntu very easy to install. from zero to a fully working audio box (for example for an art installation) i find ubuntu to be the fastest to set up (though debian might be similar, since ubuntu is only a flavor of debian).
i would like to encourage you to go the linux route, since it might be more fun, if you get everything working. in the worst case, you lose time (not money), in the best case you get the best performing setup. also, if you face problems, there usually are ways to solve them. when using proprietary OS/software/drivers, i found it sometimes hard even to narrow down the source of the problem and you are dependent on some company and their willingness to fix the problem. if it comes to optimizing your system for audio/pd use, ask again on the list.
